MACHINE FOR COVERING WIRE, CORD, ELASTIC, .AND THE LIKE.

To all whom may concern Be it knownthat I, EDWARD WARD COOPER,

a'subject of the King .of Great Britain, re-

aid of a flier it covers the gut. An obvious difliculty experienced with this process is that the length of gut, whichcan be dealt with is dependent upon the capacity of the bobbin so that when a bobbin is empty the gut has to be cut and joined up again after a new. full bobbin is put in place. Previously a number of bobbins have been used in succession, and as soon as one bobbin was empty it was destroyed. Or split bobbins were used, which could be removed when empty without damaging the gut. Even in such cases the length treated depends on the number and size of the bobbins.

By the present invention an indefinite length of gut is covered without'the empty bobbins having to be destroyed.

According tothis invention, the desired result is effected by using two bobbins of a known type which can be removed from the gut without cutting through the gut or destroying the bobbin, and I fill one while the gut is passing through it and being covered fro-m the other bobbin. Thus when the covering bobbin isempty it-is removed, and the first mentioned bobbin, which has previously been filling, is moved along the occupied by the empty bobbin. The empty put in place of the one just filled and the machine again set going so that it is refilled. Preferably special feeding mechanism is employed.

In the accompanying drawings, Figure 1 is a diagram showing part of amachine operating in accordance with this invention. Fig. 2 is a plan view bobbin which may be used.

Like letters indicate like views.

In Fig. 1 is shown a number of horizontal of one form of parts in both frame members A A A AA. which form Specification of Letters Patent.

part-0f the frame of the machine, the greater part of which is omitted for the sake of clearness Of these, the part A provides a bearing for a sleeve on which the bobbin B which is being filled is mounted. The frame member A carries a bearing for the covering bobbin C, and both bobbins are driven by belt or other gearing in any suitable manner. Thus the bobbin B is secured to a belt pulley B between which and a second pulley B runs in a horizontal plane a belt or endless band B shown in section. The pulley B is mounted upon a finger B drawn toward the pulley B by a spring. The lower end of this finger the material on the bobbin, bears against the set'screw B and pushes the pulley B aside w th a consequence that the belt B ceases to drive the pulley B The gut Z passes through the center of both bobbins B and C, and above the filling bobbin and below the ing rollers D and D The axes'of these are at r1ght angles to the gut, and the gut is gripped in each case between a driven roughened feeding roller Dand a spring mounted feeding. roller D Thus a suitable length of. gut under control is separated from the rest and the covering is effected between these two pairs of feeding rollers. In

some cases, as when india rubber is being" covered, the feeding rollers rotate at different speeds, so as to stretch the gut slightly. The gut Z is shown as being supplied from a roller X and the finished material is wound on to a roller or drum- Y. The material W from the covering bobbin C is wound on to the gut. This takes place at carries a set' screw 13. When the filling bobbin B is full gut is engaged by feed-- about midway between the two sets of rollers D and D The bobbins B and C are of such a nature that they can be removed from the gut. For instance, each may have a radial cut E Fig. 2 so that it can be threaded radially on to the gut, or they may be made in sections. Where a radial cut is used the incision E is supported by a plug F or wedge during covering, to prevent the cut closing up.

uring normal operations of the machine the upper bobbin B would be taking on the covering material from one or more supply bobbins G. The lower bobbin C would be wrapping the gut Z, which would be slowly fed through the center of the bobbins.

machine or any individual spindlewould be stopped and the position of the bobbins interchanged.

Thus when the bobbin G is empty its plug F is pulled out and the bobbin moved radially away from the gut. The bobbin B is then lowered into the position of the bob- I bin C, and the latter takes the place of the upper bobbin. and is refilled. The machine or spindle could then be started up and the empty bobbin tilled from the supply bobbin, Gin a manner which will be readily understood.

An important feature is that the gut does not require to be bent inasmuch as two or more feeding devices are used. This is important in covering wire, as two'or more strands of wire can be twisted at the same time as it is being covered. The speeds of the feeding devices may be different in the two cases so as to give any required stretch, which is used in covering rubber. The two rollers X and Y may revolve or not as required. lVhen they revolve a twist is put into the gut and then taken out again. If revolved at different speeds a certain amount of twist can be left-in the gut. The speeds of feed are varied to give the desired stretch in covering rubber.

Obviously any bobbin easily removable from the gut may be used, but the radially cut bobbin illustrated is preferred.

It will be clear that the flier H used in conjunction" with the covering bobbin must also be split radially as shown at H or be otherwise made so that it can be removed.

What I claim as my invention, and desire to-secure by Letters Patent of the United States is a 1. In a machine for coverin wire, cord, or elastic,- the combination 0 means for feeding a length of gut, a radially split covering bobbin mounted to rotate around said gut, a radially split filling bobbin mounted to rotate around said gut, a bobbin supplying said filling bobbin, said filling and said covering bobbins being interchangeable without cutting said gut, and means for refilling the filling bobbin while the gut covering operation is proceeding, substantially as set forth.

2. In a. machine for covering wire, cord, or elastic, the combination of means for feeding a length of gut, a pair of feeding rollers near one end of said gut, another pair of feeding rollers near the other end of said gut, a radially split covering bobbin through which said gut passes which -is removable without cutting said gut, a radially cut filling bobbin mounted around said gut, a bobbin supplying said filling bobbin while the wire covering operation is proceeding, said filling and said covering bobbins being interchangeable without cutting said gut, substantially as set forth.

3. In a machine for covering wire, cord, or elastic, the combinationjof a radially split covering bobbin, means for feeding gut through said bobbin, a radially cut filling bobbin mounted around said gut, a bob- I bin supplying said filling bobbin, said filling bobbin and said covering bobbin being interchangeable without cutting said gut, a belt pulley on said filling bobbin, a belt bearing against the edge of said pulley, a gripping pulley pressed against said belt, means on said filling bobbin engaged by the materialwvhich removes said pressure when said bobbin is full,substant1ally as set forth.

In testimony whereof I have signed my name to this'fspecification in the presence of two subscribin witnesses. I
